To all whom it may concern:

Be it known that I, Wninnmu Truman,-

a citizen of the'Republic of Wurttemberg, German residing at Heidenheim-on-the- Brenz, ermany, have invented certain new and useful Improvements in Separators, of which the following is a specification.

This invention relates to separators or assorting machines, and it particularly relates to a separator for assorting wood pulp, and similar fibrous material, suspended in a liquid, into different rades of fineness.

\Tiie object of the invention is to rovide means for thoroughly separating t e fine fib'ers from the coarse ones with the least amount of power. s

It is a further object of the invention to provide means which will allow the sepaa rator to turn in either direction while the water carr in the material, which henceforth is simp v called liquor is evenly charged to the annular sieve, or sieve mantle.

7 These objects are accomplished by the fol: lowin novel features of the invention:

1. y admitting the liquor into the annular sieve by passing the same first through the short entrance zone and then through a lon er rear or assortin zone, in both of which water is added a along the zones to dilute the liquorfor the purpose of preventing the material from settling on the sieve mantle, thereby clogging the same, and to completely separate t e material carried by same into the fine and coarse grades;

2. By a central stationary entrance provided with slits in its orifice, which is arran ed in an arch-like shape around the sha carrying win the shaft being journaled in suitable arings located on the outside of frame whereby stufling boxes can be dis used with;

3. y a novel basket or wheel provided with propeller wings and being of simple is (passing the machine and of the water ad ed constantly to keep the liquor in properly diluted form, the wings of the ropellen wheel can be arranged in straight cm in both the axial and radial direction, and may, therefore, run either wa The separator can be built in a orizontal as well as in a vertical construction, and fpr the better understandin of my invention I shall describe both orms, reference beinglhad to the accompanying drawings, in who 1 re resents a vertical longitudinal section of t e horizontal construction along line 11 of Fig. 2, a

Fig. 2 is a transverse vertical section along line 2-2 of Fig. 1, a a Fi 3 is a vertical longitudinal section of t e vertical construction of the separator,

Figs. 4 and 5 are sectional views showing in a somewhat enlarged proportion certain charges the liquor carrying the material to V be separated into a fine and coarse dc through its orifice, having lon 'tudina slits 2' and vertical openings 4 in t e front wall 3, into the entrance zone of the separator. The liquor is distributed radially to the shaft 5 and passes alon the hub-plate 6 of a bracket member rigid y secured in any of the well lmown ways to said shaft 5.

To the hub-plate 6 a lurality of win 7 are secured in a radial ashion around t e orifice of the entrance; this wing 7, in coaction with the hub-plate 6, forwards the li uor and passes same along wing 8, of w ich a plurality projects axially in extension of win .7 being integral with same. Said wings and 8 act as propellers forwarding the liquor both mechanicall and by centrifugal force, first through t e entrance zone and then through t e rear or assorting zone. The peripheral wall of the bracket member is perforated by means of the holes 9 throu h which water passes, conducted into the inside space of the bracket member by means of the conducting pipe 10 and is discharged throu h suitable orifices, such as a lon tudinal s 0t 11, towards the perforated wa 9.

An annular sieve mantle 14 is secured to the head lates of the standards 15 and 16 within a s lxell 17 whichis sup orted by the standards 15 and 16. Said 5 ell 17 has a lower outlet 18 for the fine grade and another outlet 19, located sidewardl at the lower edge of the su port 16, for t e coarse grade of material. tandards 15 and 16 are also provided with journals 12 in which the shaft 5 is rotatively arranged. A (pulley 13 serves for imparting motion to sai shaft 5.

When the liquor is passing between the hub-plate 6 along wings 7 towards the sieve mantle 14 the material carried by the liquor strikes first against the sieve mantle 14 and part of the material is already there separated into the fine and coarse grade, the fine grade passing through the sieve 14, while the bulk of the material, being now richer in course material, is carried by wing 8 and the flow of the water along sieve 14 to the outlet 19, while the fine grade retained by the course material is flushed with the water along and through sieve 14 and leaves through exit 18, The fiow of the water introduced by the conduit pipe 10 keeps the coarse material liquid and prevents the same from settling on the inside of the sieve mantle, thereby clogging same.

The vertical construction illustrated by Fig. 3 is easily understood on the ground of the above explanations, the exits for the different grades closely adjoining each other, the exit of the coarse material being located nearer the center, while that for the fine material is pointed in an outward direction.

While I have disclosed my invention by the embodiment described by the constructions explained above, various changes in the construction can be made without deviating from the spirit of the invention or sacrificing the advantages of same, and any such change will be considered as coming within the scope of my invention.

What I claim is:
